||The present study aims at determining the optimal and maximum quantity of the flour of worm of
manure E. foetida in the feed of fingerlings of O niloticus.
The experiment has been carried out of basins square of 1m
~ 6 ~
of volume during 45 days from October at
November 2016. During the period of acclimatization which lasted three days the fingerlings of initial
average weight 4.79 ± 0.23 g have been nourished with Coppens. They have been then subjected to five
treatments (T0; T5; T10; T15 and T20 corresponding to contents of 0%; 5%; 10%; 15% and 20% of flour
of worm of manure in feed.
At the end of the experiment the final average weights calculated was in the between 33.18 ± 13.71 g and
56.70 ± 14.65 g according to treatments'.
Thus, the variance analysis with single direction (Anova1) with Statview 5.1 indicates that no significant
difference exists between the various rates of survival. However, a significant difference between the
various specific growth rates (from 3.45 ± 0.31%/day to 6.67 ± 0.30%/day) was observed.
According to the mathematical model (amount-answer) based on the polynomial regression of the second
degree, the maximum rate of incorporation of the flour of worm of manure in feed of fingerlings of O
niloticus high out of basin under the conditions of this study was 13,82%.
